In order to ensure the overall safety of railway turnouts, it is composed of the safety of each component. Therefore, although rail fish plates are small, they play a large role in railway turnouts. For the normal operation of railway turnouts, necessary inspection and maintenance should be carried out on railway fish plates.
Railway fish plate, also known as rail joints or rail joint bar, is a connection fastener used for the connection between the track and the track. The main function is to fix the steel rail to the sleeper or rail fastening system, except for certain In addition to the pressure, it must be able to withstand the vertical force, lateral force and longitudinal force from the rail. In order to avoid the three-way force from causing excessive deformation, resulting in a large train swing, reducing ride comfort and even affecting driving safety, the commonly used types of fasteners are mostly shrapnel or rail clips, two elastic fastening systems, rail fishplates Compared with rail splice bar, it has the characteristics of following the deformation of the rail, not easy to relax, and superior in fatigue resistance.
